Deductive vs. Inductive Reasoning: A Quiz to Test Your Knowledge

📚 Quick Study Guide

• 🍎 Deductive Reasoning: Starts with a general statement or hypothesis and examines the possibilities to reach a specific, logical conclusion. Think of it as "top-down" reasoning. If A = B, and B = C, then A = C.
• 🔬 Inductive Reasoning: Makes broad generalizations from specific observations. Essentially, you start with specific data points and extrapolate to a broader conclusion. It's "bottom-up" reasoning.
• 🧪 Deductive Reasoning: Guarantees the conclusion if the premises are true.
• 📈 Inductive Reasoning: The conclusion is likely, but not guaranteed, even if the premises are true. It's based on probability.
• 💡 Key Difference: Deductive reasoning proves a conclusion, while inductive reasoning supports a conclusion.
• 📝 Example (Deductive): All men are mortal. Socrates is a man. Therefore, Socrates is mortal.
• 🌍 Example (Inductive): Every swan I have ever seen is white. Therefore, all swans are white. (Note: This is famously false; black swans exist!).
